Rigo goes 3-0. Outside of Gomez, Fenech, Pac, and maybe MAB/Morales, there's no other 122 pounders i see beating prime Rigo. Obviously, this doesn't account for Jofre and Olivares, who could have competed at super bantam had it existed, but you get my point. I guess I should add Hamed, who would have a puncher's chance. But the African trio would all be outclassed.
Ncita's pressure would probably cause Rigo a few issues before he's rendered unconscious. I can definitely see Rigo having to grind that one out, and look for his brutal left. Bungu would also likely cause him issues, but I think Rigo's power would lower Bungu's workrate like Hamed's did. Rigo should just be able to jab and move his way to a clear decision, or KO him while up on the cards. I have a hard time seeing Ledwaba get very far trying to out-box Rigo. Can't see that one at all TBH, but I do think Ledwaba is an underrated technician. Gomez, Fenech, Morales and Pacquiao are the only fighters I'd solidly favour over Rigo, but I'd give Barrera the slight edge as well.
